I guess they generates SERVFAIL on your recursor.
Maybe you can start from there.
I have no enough developed my environment, so I deal with that with a bash script which reads the recursor log file and takes the appropriate decision, sending to dnsdist the corresponding command.
I hope you will have luck, I also would be good for me.

Subject: [dnsdist] Block Random queries
My server receives some random queries as xfz3421xc.domain.com<http://xfz3421xc.domain.com>, jh65jj3e.domain2.com<http://jh65jj3e.domain2.com>
Can someone suggests some LUA script to block these kind of random queries?
